The whole conversation started because I don’t like the word “tomboy.”

“Mommy,” my daughter Emilia said to me one day a few months ago, “I think that I’m a tomboy.”

“What makes you say that?”

“Because I like a lot of things that boys like. I like basketball and motorcycles. I like surfing.” She thought about that for a minute. “I mean, girls like surfing too and lots of sports. And I like other things that girls like, like dolls. But mostly I like things that boys like. And Story (her best friend) is a boy. So. I think I’m a tomboy.”

“I wouldn’t call you a tomboy, sweetie. I think that you’re you. And you like a lot of different things, and they’re not just ‘boy things’ or ‘girl things,’ they’re things that you like.”

“But you could call me a tomboy.”

“But I wouldn’t.”

“But if you did … ”

“I’ll just keep calling you Emilia.”

And that, I thought, was that. Conversation closed; no more talk of tomboys.

But then she asked me about it again, a few weeks later, after a friend (a girl) described her as a tomboy. And then a few weeks after that, she asked me what a “bad-ass” was. She had seen the word, underneath an Instagram photo of her in dirt bike gear, on my phone.

And then just a few days later, she asked me what Hilary Clinton is. (In other words, is she a tomboy, a bad-ass, etc. Emilia’s answer: “She’s a bad-ass, Mommy.”) It wasn’t until we were well into a months-long conversation about all of these things that I realized we weren’t really talking about tomboys.

We were talking about feminism.

If you’d asked me, at any point in the last eight years or so, if I talked to my children about feminism — about girl empowerment, about gender equality, about gendered narratives in media, etc., etc. — I’d have told you that I talked to them about it all the time. When we talked about why I wouldn’t buy Bratz dolls. When we talked about Jasper’s love for princesses. When we talked about Mommy going to work and Daddy staying home. When we talked about a lot of things. But it wasn’t until Emilia demanded to know — in not these precise words — what it all had to do with her. With what it all has to do with who she is, and how she sees herself, and how others see her, and all the complicated questions in between.

I mean, look: by most conventional standards, Emilia is absolutely what is often called a tomboy. She does like things that are culturally coded as “boy” things. She likes sports, she likes adventure, she likes action; she’s all skinned knees and torn pants and messy hair. She surfs, she skateboards, she rides a dirt bike. There are some “girl” things that she likes — mess with her American Girl dolls and she’ll cut you — but she enjoys those things in a context that is, for lack of a proper term, gender-complicated. Her favorite American Doll sits in a doll-sized wheelchair because “she hurt herself on her motorcycle.” Her princess costumes are worn with skate shoes and Buzz Lightyear wings. Taylor Swift concert stickers decorate the bottom of her skateboard.

We used to call girls like Emilia “tomboys.” But I hate that word, and I told her so. I told her that I didn’t like comparing her to boys. I told her that I didn’t like thinking of things as “boy things” and “girl things,” and that I certainly didn’t like any suggestion that “boy things” were somehow better. I told her that there was a long history in the world of “girl things” being treated as less important than “boy things” and that that was a problem for everyone — not just girls.

“Because what happens if you’re a boy – like Jasper – and you like kittens and My Little Pony and people say that’s bad or silly or wrong?”

“You feel bad.”

“Exactly.”

It really is as reductive as that, I think, when it comes to discussing why gender stereotyping is a problem: it makes people feel bad. It makes them feel limited. It constrains their own understanding of their horizons of possibility. It tells them, you have to fit inside these boxes, and don’t you dare step out of line. And it does this to girls and boys, women and men.

Which is why feminism is for everybody, although I didn’t put it to Emilia in exactly those terms. If feminism can be understood, in part, as a commitment to and/or belief in allowing everybody the freedom to define who they are — and to direct their life on the basis of that definition — without restriction of gender conventions, then, yes, it’s for everybody.

It’s especially for children, because that’s what childhood is about: discovering and defining yourself. Crafting your own story, and telling that story, and then changing that story and telling it differently. Such that having access to the fullest range of possibilities — liking pink AND brown, sharks AND kittens, princesses AND pirates, ballet AND baseball — matters tremendously. The scope of who our children can be narrows or widens depending on the degree to which we do or do not challenge gender stereotypes.

It’s why fighting the pink aisle matters. It’s why demanding more women (and more women of different cultures and colors and body types and abilities) in media matters. It’s why pushing for more women in leadership positions in politics and business matters. It’s why celebrating women in sports and in STEM — and men who stay at home or become nurses or teachers — matters. It’s why talking about this stuff with our kids matters. So that they know that they should not feel limited by their gender when they think about who they are or what they dream about or what they could become. So that they can grow up believing that all things are possible, and fighting (because it does still require a fight) for all those things is possible.

This is why I never use the word “tomboy” with Emilia. Because she’s not a tomboy. She’s so much more than any one type, never mind a gendered one. She’s a girl, sure, but she is, to borrow from Whitman, large and contains multitudes.
